i just bought the multi flip 13a and it is awesome! the 15 inch model was a bit too big and not practical to use as a tablet. and by taking the 13a model with only intel graphics i was sure that the screen and driver are exactly the same as the vaio pro 13.... finally a tablet and laptop with touchscreen that does not hurt my eyes (even powered on with current).

thank you SONY

and now i will contact sony to ask if they can give a hint or tip for the root cause of this eye-issue. tbc

A collegue of mine allowed me yesterday to work with her Sony Multi Flip 13A (Triluminus/Intel). I worked for around 4 hours in the evening doing my regular job.

My experience is as follows:

on battery the device seems to be easy on the eyes, almost like using the old good ccfl laptops

plugged-in the device seemed to be a bit more aggressive to my eyes. A hour of work caused me a bit of a discomfort, BUT nonthing like the Macs or any other led display mentioned in the forum i.e. no burning eyes or headaches, just a mild discomfort that i can say went away after 20 mins of rest.

All in all, i conclude based on my 4 hour experience that if someone needs a new device desperately and cannot wait for future developements, i would say that it is a device we could use, maybe with rests between use especially when plugged in.

For Apple fans, I dont like Win 8 at all, i found it a bit confusing in the way it is structured. I wish Apple could construct a similar device.

Ok, I went to Best Buy and viewed a 14inch Trimulous display for a solid 5-10 minutes and I can say it was greatly better than most any other LED back lit device I have been exposed to. I believe with my anti-glare coating at home it may be tolerable for periods of time but I am not certain. I will be purchasing the 13A model soon and will trial it for the 15 day return period. The manager of the PC area was actually very supportive in helping me understand the display on the floor was the same as the 13A model and had no issue with a 100% refund within 15 days should I order the 13A.

By comparison with what I have read and heard from people here and on my web site I believe I am one of the most sensitive to LED light so I can set the bar pretty well for how effective the display is.

As for understanding why it is effective I cannot give a scientific reason however here is my theory based upon reading about the Trimulous technology:

Using quantum dot technology the screen is "filtering" out harmful blue light spectrum, it essentially uses the opposite wavelength to cancel out the harmful blue light according to the computer tech I was speaking with at the store. I do not completely understand the latter part of this statement on wavelength however it makes sense that Sony has found certain blue wavelengths in the LED spectrum that are causing color rendering issues, in order to improve color accuracy they may have knowingly or unknowingly created a healthier display.

This is my opinion and obviously not science based facts. I will say regardless of the reason, the display has a much better appearance to me and feels much cleaner than anything else out there I have tried! Very exciting, I will report back after some serious usage in my home, with and without anti-glare glasses, testing results coming soon!

I have no big hopes on the Z2, I have already tried the Z1 with kind of same result as with the plugged in Vaio Pro 13 (OK for some time).

I still stick to my theory that the GPU driver plays some role as well and it seems that all Qualcomm phones/tablets are bad for my eyes. However the Z1 was better than any other Qualcomm devices I have tested, so thumb up for Sony Triluminos, too bad that Sony sold the Vaio .

Somebody here said HTC OneX and Galaxy Tab 3 are OK. They both don't use Qualcomm. On the other side iPads/iPhones also not using Qualcomm as well and still not good...

I'm indeed pretty sure it's contrast. Brightness is not an issue as well as PWM (I tried shades with 100% brightness and it does not make any difference). First my eyes get not strained by an intensely flickering TV.

Second my old Vaio Notebook exhibits Flickr recognizeable by my smartphone and it does not bother me.

The only real difference seems to be the way whites and blacks are displayed.

So for me there are just two factors:

- contrast

- light spectrum

I feel it that it is contrast, it's just the whites are too white, they disturb our eyes from

I know PWM can be measured at 100% brightness but it should dramatically decrease and at least I don't recognize any difference. I can confirm that whites are the worst for me, too. They are killing my eyes.

To answer the question: No, my Vaio has just a cheap TN-Panel, I can look at it the whole day. As I already mentioned it has significant less contrast than modern devices, 170:1. Whites don't disturb, they look flat and not straining, just pleasing as reading a book.
